    The present invention relates to a solid wood panel with at least two, in particular with several, solid wood boards, the solid wood boards are longitudinally extended in the direction of their wood fiber and two, in the direction transverse to their wood fiber adjacent to each other arranged solid wood boards abut each other and are glued together. 5
    Solid wood panels of the type mentioned are known in the art. They are made by usually several solid wood boards are glued together side by side. Generic solid wood panels can be used as table tops but also for other purposes. For many applications, however, gluing 10 of the solid wood boards is not sufficient to equip the finished solid wood panel with the required stiffness in the direction transverse to the wood fiber. In order to achieve the required stability in the direction transverse to the wood fiber, it is known to milled channels on the underside of the massive plate, are used in the ridge strips. Another, known in the prior art approach is to screw T-shaped iron rails in a mostly 15 also attached to the underside of the solid wood panel groove. In addition, it is also known to provide reinforcing profiles, in particular on the underside of the solid wood panel. The known in the prior art approaches to increase the stiffness of the solid wood panel in the direction transverse to the wood fiber have two major disadvantages. On the one hand, they visually influence the external appearance of the Mas-20 sivholzplatte. On the other hand, they often affect the stiffness of the solid wood panel in the direction of their wood fiber.
    The object of the invention is to propose an improved solid wood panel with respect to the problems mentioned. 25
    This is achieved according to the invention by forming in at least two solid wood boards arranged adjacent to each other at least one receiving cavity which is completely invisible from the outside and extending transversely to the wood fiber of the solid wood boards and at least one from the outside in the receiving cavity. 5 • ♦ ···· « ** · · ^ - · ·. It is also completely invisible and arranged longitudinally in the direction transverse to the wood fiber of the solid wood boards, as well as continuous reinforcing body. 10 15 20
    It is thus a central idea of the invention to form a receiving cavity transversely to the wood fiber of the solid wood boards, which from the outside completely invisible, so when viewing the solid wood panel from the outside is not visible, no matter from which side of looking at the solid wood panel. The receiving cavity is formed according to the invention throughout, i. it extends as a contiguous receiving cavity in the direction transverse to the wood fiber on at least two, preferably several solid wood boards. Within the solid wood boards, the receiving cavity is thus formed as a coherent cavity. In this, a longitudinally extending in the direction transverse to the wood fiber of the solid wood boards, also continuous reinforcing body is arranged. The reinforcing body thus also extends continuously, so as a continuous reinforcing body in the direction transverse to the wood fiber on at least two, preferably more, solid wood boards. In general, it should be noted that a solid wood panel according to the invention has at least one correspondingly formed receiving cavity with at least one reinforcing body arranged therein. As a rule, however, the solid wood panel has a plurality of receiving cavities according to the invention arranged one behind the other and viewed in the direction of its wood fiber and spaced from one another, in each of which at least one reinforcing body is arranged. It is even conceivable that a plurality of elongated and continuous reinforcing body are arranged according to the invention in a single receiving cavity.

    The solid wood boards of the solid wood panel are, as the name implies, preferably 25 exclusively, made of solid wood so solid wood. This means that the solid wood boards are a board-type wood product in which the boards are e.g. worked out by sawing from a tree trunk and, if necessary, have been subsequently machined. An essential feature of these solid wood products is that in them the natural fibrillation, as it was present in the tree trunk, 30 still remains over the entire extent of the board. This distinguishes the solid wood products substantially from particleboard and the like. Due to the still existing in the solid wood board natural wood fiber, this natural product has essentially also the natural wood properties, especially so the natural swelling and shrinkage behavior of the wood in moisture and / or temperature change. 35 The solid wood boards are also referred to in specialist circles as solid wood friezes. 3
    Since the solid wood boards are a natural product, it is clear that the direction of the wood fiber or the fibrillation of the wood is not exactly linear. Rather, it is a preferred direction, which in a kind of averaging reflects the course of the fibrillation in the wood. Of these, there may be deviations especially in the area of branches and the like. Nevertheless, it has prevailed in the professional circles that one speaks of the direction of the wood fiber and the direction across the wood fiber. The term "cross" First of all, it defines the fact that it is a deviation from the parallels. In particular, however, the receiving cavity and the reinforcing body may be substantially orthogonal to the direction of the wood fiber. Due to the fact that the solid wood boards in the direction of their wood fiber their greatest extent, so have their longitudinal extent, one could designate the direction of the wood fiber as a longitudinal direction and a direction across the wood fiber as Guerrichtung. 15 experiments have shown that with the Ausgestattungsformen invention
    Solid wood panel whose stiffness across the wood fiber can be significantly improved without their rigidity in the longitudinal direction or in the direction of the wood fiber is significantly impaired. Another important advantage of the invention is that in the finished solid wood panel from the outside neither the receiving cavity nor the Verstärkungskör-20 are visible by and thus the visual appearance of the solid wood panel is not disturbed. On the known in the prior art, visible from the outside and thus affecting the appearance of the solid wood panel reinforcing measures can be completely eliminated. Solid wood panels according to the invention can be used as table tops but also in any other applications, e.g. used in furniture construction. Conveniently, according to the invention, it is provided that a ratio between a flexural elastic modulus of the reinforcing body in the direction of its longitudinal extent and a flexural modulus of elasticity of one of the solid wood boards in the direction transverse to the wood fiber is between 10: 1 and 1000: 1, preferably between 70: 1 and 700: 1 , is. The flexural elasticity modulus can be determined according to ÖNORM EN 310: 2005-12 in a 3-point bending test. The reinforcing bodies can basically be designed in different ways. Preferred embodiments provide that the reinforcing body is rod-shaped or tubular. For example, For example, the reinforcing body may comprise or consist of a metal, preferably steel. But it is just as well conceivable to form the reinforcing body so that it preferably comprises fiber-reinforced plastic, or consists thereof. ·· * ·· * · ·· ♦♦ * * · J_ * · «*» # * * #
    The last-mentioned embodiments have the advantage that if, during processing of the solid wood panel, it is inadvertently cut too deeply into it, so that the saw blade hits the reinforcing body, the plastic of the reinforcing body is also sawed, and thus no impairment or destruction of the saw blade comes 5
    Preferred embodiments of the invention provide that the reinforcing body is loosely inserted into the receiving cavity. This means, in particular, that the reinforcing body is not screwed, glued or the like in the receiving cavity. Insertion into the receiving cavity preferably results in a frictional engagement between the reinforcing body and the receiving cavity. Further attachment of the reinforcing body in the receiving cavity is conveniently not provided. It can e.g. be provided that the reinforcing body rests on at least one bead from penetrated into the receiving cavity and cured adhesive. By appropriate choice of material in this context, e.g. be achieved that the reinforcing body 15 rests only on the bead frictionally and is not glued to the adhesive. By a corresponding frictional engagement can also be prevented that the reinforcing body is moved when moving the solid wood panel in the receiving cavity back and forth, whereby an undesirable noise is prevented. 20 For producing solid wood panels according to the invention is advantageously provided that initially corresponding portions and / or blind holes of the or each receiving cavity formed in the solid wood boards, preferably drilled or milled into this, then the or the reinforcing body are inserted into the respective sections and thereafter the mutually adjacent 25 arranged solid wood boards are glued together. For bonding the solid wood panels together, a wide variety of known per se adhesives can be used, in particular, it can be glue, ie an aqueous solution of an adhesive. Other features and details of preferred embodiments of the invention will become apparent from the description of the figures. Show it:
    Fig. 1 is a schematic representation of a solid wood panel according to the invention;
    2 and 3 different embodiments of cross sections along the section line AA of Fig. 1 and 35 • · ······················································ 5
    Fig. 4 shows a part of a longitudinal section along an interface between two adjacent solid wood boards.
    1 shows a schematic perspective view obliquely from above of a solid wood panel 1 made in accordance with the invention. The hollow receiving spaces 6, which are not actually visible from the outside, with reinforcing bodies 7 arranged therein are shown to illustrate the invention. The solid wood boards 2 are thus virtually transparent in the area of the receiving cavities 6. The solid wood panel 1 has at least two, here several, solid wood boards 2. The
    Wood fiber 4 is present in the respective solid wood boards 2 still in their natural form. Each solid wood board 2 has two opposing top surfaces 15, two opposite side surfaces 14, and two opposite end surfaces 16. In general, the top surfaces 15 are larger than the side surfaces 14 and 15 these in turn larger than the end faces 16 of a respective solid wood board 2. Die
    But solid wood boards 2 can also be made relatively narrow, so that the side surfaces 14 are larger than the top surfaces 15 and these in turn are larger than the end surfaces 16. The solid wood boards 2 are longitudinally extending. This means that their length 18 is their biggest dimension. In general, the length 18 is greater than the width 17 and this as-20 in turn greater than the thickness 10 of the respective solid wood board 2. It can also be provided that the thickness 10 is greater than the width 17, wherein these two dimensions again smaller than the length 18 of the wooden board.
    Each adjacent solid wood boards 2 of the solid wood panel 1 lie with their Seitenflä-25 surfaces 14 to each other and are glued together at these side surfaces 14. The adjoining side surfaces 14 together form the interface 19. The direction 3 of the wood fiber 4 coincides with the direction of the longitudinal extent of the solid wood boards 2. The direction 5 across the wood fiber 4 is the direction in which the receiving cavity 6 and the reinforcing body 7 are longitudinally extended. 30
    In the embodiment shown, two parallel receiving cavities 6, each with a reinforcing body 7 arranged therein, are provided in the solid wood panel 1 by way of example. However, the number, the spacing and orientation of receiving cavities 6 and reinforcing bodies 7 arranged therein can be adapted to the rigidity values to be pursued for the particular solid wood panel 1. For example, it is conceivable to provide at least one but also several receiving cavities 6 with corresponding reinforcing body 7 per running meter of solid wood panel 1 in the direction 3 of the fiber 4. Test panels were produced to a length 18 of two meters three receiving cavities 6 each provided with reinforcing bodies 7 are provided. 10 15 20 25
    2 and 3 show sections in the direction 5 transverse to the wood fiber 4 through one of the receiving cavities 6, wherein FIGS. 2 and 3 represent different embodiments of the invention. The respective section line is marked AA in FIG. In the embodiment according to FIG. 2, it is provided that the receiving cavity 6 ends, preferably at its two ends 11, at an interface 19 between two solid wood boards 2 arranged adjacent to one another. In order to achieve this, the partial areas 13 of the receiving cavity 6 are formed in the middle solid wood boards, while the outer solid wood boards 2 in their original Keep shape, so have no portion 13 of the receiving cavity 6. Notwithstanding this, an embodiment is shown in Fig. 3, in which at least one end 11, preferably both ends 11, of the receiving cavity 6 in the form of a blind hole 12 are formed. These blind holes 12 are conveniently again in each outermost solid wood board 2. The respective sub-areas 13 and blind holes 12 are first formed in a first step in the respective solid wood boards 2. Manufacturing technology is simple and therefore cost-effective, if one drills the respective portions 13 of the receiving cavity 6 and the blind holes 12 in the respective solid wood boards 2. In this sense, it is preferably provided that the receiving cavity 6, preferably over its entire longitudinal extent transverse to the wood fiber 4, has a circular opening cross-section. Although this may not necessarily be so in this combination, but it is also beneficial in this context, when the reinforcing body 7, preferably over its entire longitudinal extent transverse to the wood fiber 4, has a circular cross-section. «·« · ♦ · »9 9

    Of course, other cross-sectional shapes can be formed by suitable milling operations or the like. After the introduction of the subregions 13 and / or the optionally required blind holes 12, the reinforcing body 7 is advantageously inserted into the respective subregions 13 and possibly blind holes 12 of the receiving cavity 6. Subsequently, the solid wood boards 2 at their Grenzflä- 35 h

As a result, then in Fig., 2 and 3 particularly clearly visible inventive arrangement in which the respective receiving cavity 6 in the direction 5 extends transversely to the wood fiber 4 of the solid wood boards 2 along and is formed continuously and in the receiving cavity 6 in a 5 5 transverse to the wood fiber 4 of the solid wood boards 2 longitudinally extended, and continuous reinforcing body 7 is arranged, wherein neither receiving cavity 6 still reinforcing body 7 are visible from the outside.
    The extension 9 of the opening cross section of the receiving cavity 6 in the direction parallel 10 to the thickness 10 of the solid wood board 2 and the solid wood panel 1 should favorably between 50% and 70%, preferably between 55% and 65%, the thickness 10 of the solid wood board 2 and the solid wood panel 1 amount. The areas of solid wood remaining above and below the receiving cavity 6 should desirably be of the same thickness. They ensure that the bending stiffness in direction 3 of the wood fiber 4 is maintained to a sufficient extent. In other words, the receiving cavity 6 should thus be arranged centrally in the respective solid wood board 2 with reference to the direction parallel to the thickness 10. The maximum diameter of the reinforcing body 7 may be at least 95%, preferably at least 96%, of the maximum diameter of the receiving cavity 6. However, in order not to disturb the swelling and / or shrinkage of the solid wood board 2, the diameter of the reinforcing body 7 should be at least 1%, preferably at least 1.5%, smaller than the maximum diameter of the receiving cavity 6. the receiving cavity 6 is designed as a bore with a diameter of 25.8 mm and the diameter of the reinforcing body 7 used was 25 mm. 25
    In order not to disturb natural shrinkage and swelling processes of the solid wood boards 2, the length ratio between receiving cavity 6 and reinforcing body 7 is similar. Again, it is conveniently provided that the reinforcing body 7 extends over less than 100%, preferably less than 99%, of the extension of the receiving cavity 6 in the direction 30 transverse to the wood fiber 4. On the other hand, the reinforcing body 7 is the
    Naturally, completely stiffen the receiving cavity 6. In this sense, it is favorable if the reinforcing body 7 extends over at least 95%, preferably over at least 98%, of the extension of the receiving cavity 6 in the direction 5 transversely to the wood fiber 4. _ · · * ················································································································································································
    Fig. 4 shows a schematic longitudinal section along an interface 19 in the region of the receiving cavity 6. There it can be seen that when gluing the respective adjacent solid wood boards 2 adhesive has penetrated into the receiving cavity 6 in order to form the bead 8 there. The reinforcing body 7 is frictionally engaged on the bead 8 and otherwise loose in the receiving cavity 6. By appropriate choice of material of the reinforcing body 7 prevents the bead 8 forming adhesive adheres to the reinforcing body 7. As a result, thermally induced or moisture-related relative movements between solid wood and reinforcing body 7 can be compensated. Nevertheless, the reinforcing body 7 but does not slide in the receiving cavity 6 back and forth when the solid wood panel 1 is moved, since it is indeed frictionally held on the beads 8. ··· »• • • • f« ♦ · • ♦ * * • · · M ··· * · · ♦ Φ ·· ♦ · 10 / _ «· · ······ ♦ ·» »%» " ' »* * · -» - • · · · - · - • · «··« ································································································································
